Q: The AD7606 seems to be operating in half the range I am setting. What am I missing?


A: Check how you are setting the range pin, as this should not be changed at the same point as issuing a valid CONVST command. There should at least be 80us between changing RANGE pin and a valid CONVST signal. Also note that the RESET command should be initiated after the valid powerup time.
